🏢 About Hellyeah AI

Hellyeah is the agentic operating system for distribution. AI agents plan, execute and optimize growth work, and humans approve it. A small engineering team runs several live products, with coding agents as part of how we ship.

🎯 The Role

You will own the platform our products and agents run on: the gateway every model call passes through, the runtime for our production agents, and the clusters, data stores, pipelines, secrets and release paths underneath.
We're hiring two engineers, one in San Francisco and one in Shanghai. One will lean toward the AI platform and the other toward the core platform. You'll share ownership and on-call, and work closely with our CTO.
This role is onsite five days a week. On-call includes nights and weekends, and days often run past 10 hours.

✅ Key Responsibilities

• Run the model gateway. Own routing, fallbacks, provider failover, rate limits and rollouts for 90+ model deployments across OpenAI, Anthropic, Azure, Google and AWS Bedrock.
• Make the gateway multi-tenant. Give each team and customer the right keys, routes, limits and usage metering, and reconcile usage against provider invoices.
• Run the AI developer platform. Own shared coding-agent access, including seats, quotas and per-user limits, plus the remote workspaces our engineers use.
• Run production agents safely. Own sandboxing, credential scoping and pinned releases for long-running agents on Kubernetes.
• Automate your own job. Expect to build a lot of autonomous infra workflows and infra agents that take on routine requests and alerts, with a person approving risky actions.
• Own infrastructure and AI spend. Reconcile provider bills against usage, tie spend to a team and product, and catch anomalies early.
• Keep clusters and cloud healthy. Debug and upgrade EKS, AKS and bare-metal k3s through Argo CD and Kustomize.
• Run the edge. Own Cloudflare across a dozen domains: DNS, WAF, TLS, CDN and object storage, plus GeoDNS, load balancers, egress IPs and email authentication.
• Ship new services fast. Point a coding agent at an open-source repo and have it in production the same day: manifests or Helm, pinned images, Postgres and Redis, SSO, DNS, TLS, secrets and backups, all through GitOps.
• Lead migrations. Move workloads between regions, clouds and platforms with a tested rollback, retire what's left behind, and bring stray services under GitOps.
• Operate the data layer. Upgrade and migrate production PostgreSQL, MySQL, ClickHouse and Redis, run schema changes safely, and prove backups by restoring them.
• Keep data pipelines flowing. Run Airbyte, Airflow, Dataform and CDC into BigQuery so product and finance data stay fresh.
• Own reliability. Set SLOs and alerts people trust, lead incidents across infrastructure and product services, including realtime speech, write the reviews, and automate the triage you keep repeating.
• Own observability. Keep metrics, logs and traces flowing and usable across every cluster and the gateway.
• Own infrastructure security. Rotate credentials, replace static keys with workload identity, find exposed secrets and vulnerable dependencies, respond to exposures, and control access to customer data.
• Make access self-serve. Replace manual grants with SSO, workload identity and scoped secrets, so engineers get what they need without asking you.
• Give product teams a paved road. Build the release pipelines, canaries, preview environments and guardrails that let them ship and operate their own services.
• Review and teach. Review infrastructure changes from engineers, founders and their agents, and share the runbooks and agent skills that keep everyone fast.

📌 Required Qualifications

• 5+ years running production infrastructure, with real on-call experience
